| 摘 要： | 由于兴趣区域为前景图像区域,聚焦区域选择算法需要选择前景图像区域作为聚焦窗口,目前大多采用对前景图像区域进行估计的方案.论文分析了中心取窗、多点取窗等方式的优缺点,并提出了图像非均匀采样窗口区域选择算法.

| Abstract: | The foreground image had to be chosen as focusing window while selecting the focusing window,since the interested region was mostly the foreground image.And the method of estimating the foreground region was mainly adopted to get focusing window.Advantages and shortcomings of several algorithms,including centre region selection and multi-region selection were given in the paper,and the un-uniform sampling region selection was also proposed. |

| Keywords: | focusing window un-uniform sampling focus measurement function image processing |
